To all whom it may concern:

Be it known that I, WILLIAM A. KNn MAN, a citizen of the United States,residingat Cudahy, in the county of Milwaukee and State of Visconsin,have invented a new and useful Improvement, in Vehicle-Tires, of whichthe following is a specification.

My invention relates to thatA class of vehicle-tires wherein a solidtire formed of rubber' or analogous material has lateral flanges for thepurpose of securing it to Athe wheel and is provided at intervals` withtransverse metal inserts molded/in the tire and extending through thesame at its flanges for the purpose of alliording to the tire a moresecure fastening. ln tires of this type as heretofore provided and incommon use, these inserts are of such shape in cross-section as to tend,under the kneiuling action to which the rubberis subjected while thewheel is in use, to wear or cut through the tire to the rim, resultingin destroying their etliciency as a holding` medium and rin permitting,the tread and flange to become cracked, ortorn apart, or in allowingthe flanges to spring out from their locked eiigagement \vitli tlicclamping rings, thereby greatly shortening the life of the tiro.

My object is to overcome these faults, and to that end I construct atire in which in serts are used of such form in transverse section andarranged in suoli spaced relation to each other as toi reduce to theminimum the Wearing and cutting tendencies referred to, and even in theevent of such cutting yeventually taking place, to still retain such ahold or lock upon the rubber as to maintain it in place upon the wheeland thus per mit the maximum wear oit' the tire.

My invention is illustrated in the accompanying drawings in whicl1-Figure 1 is a view in broken side elevation of a portion of a wheel;Fig. 2 is an enlarged broken View in side elevation of a portion of thetire showing two of my inserts in their preferred form in positiontherein; Figs. 3, et and 5 are views similar to Fig. 2, showing otherforms of inserts suitable to my improvement; Fig. 6 is a View intransverse section taken at the line 6 on Fig. 1; Fig. 7 is a Viewsimilar to that presented in Fig. 6, but showing a double, or dual tireembodying my improvement; and Figs. 8, 9`, 10 and 11 are perspectiveviews respec and 5.

The tire comprises a tread-portion 12 and.

lateral flanges 13 projecting beyond the body-portion thereofsufficiently to provide requisite clamping surfaces for the attachmentof the tire to the wheel. Metal inserts 1l are molded in thcbase-portion of the ,tire in .its formation and are preferably of such alength as to extend at their ends justl flush with the outer edges ofthe flanges and are so disposed that their outer surfaces are llush withthe peripheral faces of the flanges. The tire is placed about the rim 15surv rounding the felly 16 of a wheel and clamping-rings 17provided withlips 1S, are fastened on opposite sides of the felly so that the lipsoverlap and engage the tlangcs 13. The rings are securely held inposition, as by bolts 19 passing at intervals through the rings andfolly. The extreme width of the tire over all at the llanes preferablyjust equals that of the rim which it surrounds, and the outer edges ofthe flanges and ends ol" the inserts impinge against the inner faces ofthe rings at their line to form a sung lit and thereby' prevent anylateral movement of the tire when in a normal eon.

dition. .From the lip the inner .face of each ring recedes'and forms anoblique face extending to an annular shoulder 20 which meets theperiphery of the rim to provide a tapering recess 21 bctween'the flangeand adjacent face of the clamping-ring. This space allows freedom ofmovement ot the flanges between the rim and lips, underhthccon'ipression of the tire, and insures a rigid seat for the impingingedge of the flanges when the tire is in its normal condition.'

.When itis desired to provide a tire for heavy trucks, or the like, orwhere for other reasons it is essential to have a wheel with a wideface, l refer to use a double, or dual tire, each mem er thereof beingof the form shown in Fig. G. These members are applied to the .wheel rimin the same manner as the tire previously described and as 1llustratedin Figr, and the outer flange of each tire-member is similarly held inplace by a clamping-ring- For confining the adjacent inner flanges ofthe tire-members in place, a band 22 is secured about the rim centrallythereof. The inner flanges 23 of thisband are preferably beveled fromthe web 24 to form thin edges, and the outer flanges are rim with. theirinner flanges crowded to theirV .seats within the' flanges of theband22.

VF or maintaining the tire in position upon the wheel through the mediumof the metal reinforcing inserts, I adopt inserts of such form incross-section,'and so position them about the tire, that they maintain alocked engagement with the tire itself regardless of whether they cutthrough the tire or not, but I employ inserts of such form aswill tendto avoid the cutting action referred to.l To illustrate: Assuming theV-shape inserts lll shown in Fig. 2, to be live-eighths of an v inchacross the sides 27 with three-quarters suming that, under the action towhich thetire is subjected in use, the points 28 shouldl of an inchspace between the sides of adjacent inserts, this would provide adistance ofone and three-eighths inches between the apexes 28 of theadjacent inserts. Now aseventually cut through the tire, as indicated bydotted lines, a head 29 of one and threeeighths inches in width wouldstill remain between inserts, with each head connected with thebody-portion of the tire by a neck 30 equal tothe space between theedges of the saine inserts, or three-quarters of an inch. Thewidth ofthe head being so much greater than that of the neck, suicientcompression of 'the head-portion could not take place to permit it t0 bewithdrawn from between inserts, with the result that the heads fornianchors for the tire to prevent such separation. Vl `or iimiting thecutting action, such form of insert is used as will present a surface tothe rubber between it and the rim, having an area sufficiently great tooffer a resistance in exc-ess of the force of compressionof the rubberat the tread. The ifshaped inserts*l 14; afford one form' for thepurpose. In Fig. 3, lJ-shaped inserts 31 are shown, while in Fig. 4l,channel-inserts 32 are represented, which are preferably arranged inpairs; and in Fig. 5, T-shaped inserts 3 3 are illustrated as formswhich may be employed. By referring to the various figures it will beobserved that much the same headA or anchor isformed between thedifferent inserts. In the form shown in Fig. Il, however, the head iscontained within the pairs of channels, though in all forms theneck-portion ofthe anchor, which is 4characteristic of my improvement,is formed betaperin steers tween flanges or adjacent edges of theinserts.

l. In combination, a vehicle-tire provided with lateral flanges formedwith cylindricall upper Surfaces land sides extending at a right-anglethereto, inserts extending cross- What I claim as new,'and desire tose-v cure by Letters Patent 1s wise of the tire, a supporting rim forthe wardly tapering from the lips, whereby a v space is formed betweenthe sides of the flanges and said clamping-ring, and means for securingsaid clamping rings in place, for the purpose set forth.
